Question

which factors were typical of dust bowl conditions in the 1930s?
rain storms and crop failures
dust storms and falling crop prices
debt and successful crops
droughts and fertile farmland

Explanation:

The Dust Bowl in the 1930s was characterized by severe dust storms due to drought and poor farming practices, and falling crop prices as agriculture struggled. Rain storms were not typical (drought was), successful crops and fertile farmland were not features (soil was degraded), so "dust storms and falling crop prices" matches.

Answer:

B. dust storms and falling crop prices
